The star formation rate (SFR) density values reported in my 2004 paper for the data taken from D. W. Hogg et al. (ApJ, 615, 209 [2004]) are in error. The original cosmology conversion factor used was incorrect, and the values listed in Table 2 for both C1 and ρ˙*com are in error. Moreover, the (incorrect) value reported for C1 was not that used in calculating the (incorrect) values of ρ˙*com. The correct cosmology conversion leads to SFR density values that are smaller than those given in the original paper by amounts decreasing monotonically from ~43% for the z=0.2 bin to ~30% for the z=1.2 bin, as indicated by A. M. Hopkins & J. F. Beacom (ApJ, 615, 209 [2004]), who show an updated version of the star formation history diagram (compare their Fig. 1 with my original Fig. 1). The correct SFR density values are given here in a new Table 1, which has the same format as Table 2 of my original paper, although the table notes are omitted here. Apart from the location of the corresponding data points in Figure 1, this error does not significantly alter any of the results or conclusions of the original paper.
I thank Chun Ly for bringing this error to my attention.
